Introduction This section gives an overview of the SW HDMI Series switchers. Topics include: • About this Guide • About the SW HDMI Series Switchers • Features • Application Diagram About this Guide This guide describes the Extron SW HDMI Series switchers and discusses how to install, configure, and operate them. In this guide, the term “SW HDMI Series” refers to both the SW2 HDMI and the SW4 HDMI switchers. “Switcher” and “SW HDMI” are used interchangeably to refer to any single unit.
• Remote configuration and control — The switcher can be configured via an RS-232 or USB connection via SIS commands (see “Using Simple Instruction Set (SIS) Commands” on page 19). • EDID Minder® — A proprietary EDID (Extended Display Identification Data) management process from Extron, the EDID Minder manages the EDID between a digital display device and one or more input sources.

d Remote and auto-input switching connector — This 5-pole, 3.5 mm captive screw connector (labeled “Remote”) can be used for RS-232 communication with the switcher, including firmware updates, and to enable auto-input switching. • To enable RS-232 control, connect the Tx (transmit), Rx (receive) and G (ground) pins to the serial port of your computer (see “Wiring for RS-232 Control” on page 7). • To enable auto-input switching, short pins 4 and 5 of this connector together.
4. To verify the power cord polarity before connecting the plug, connect the power supply with no load and check the output with a voltmeter. 5. Use the supplied tie wrap to strap the power cord to the extended tail of the connector. The figure below shows how to wire the connector. Heat Shrink 7/8" (22 mm) 1/8" (3 mm) 3/16" (5 mm) Max.

Connecting to the USB Port The mini B USB port is located on the SW HDMI front panel. It can be used to configure the switcher via SIS commands. 1. Connect a USB A to mini B cable between the USB Config port on the switcher front panel and the USB port on your computer.

• Select the Yes, this time only radio button if you want your computer to connect to Windows Update only this one time. • Select Yes, now and every time I connect a device if you want the computer to automatically connect to Windows Update to search the web every time the switcher is connected to this USB port. • Select No, not this time if you do not want the computer to connect to Windows Update to search the web at this time (for example, if the driver is already on your computer). 3. Click Next.
Enabling Auto-input Switching You can set up the SW HDMI to automatically select the active, connected input based on detection of an active video signal (TMDS clock activity). If two or more inputs are active, the input with the highest number is selected (for example, input 4 on an SW4 HDMI switcher). When auto-input switching is in effect, the green Auto Switch LED on the front panel lights and the front panel input selection buttons are disabled. To enable auto-input switching: 1.

c Input selection buttons and LEDs — Press these buttons to select input 1 or 2 or inputs 1 through 4, depending on your model. The LED at the right of each button lights when the corresponding input is selected. These buttons are disabled if auto-input switching is in effect; however, the LEDs continue to light to indicate the selected input.
Operations Powering on the Switcher To power on the SW HDMI: 1. Connect all input and output devices to the rear panel connectors on the switcher (see “Rear Panel Features” on page 5 for the rear panel connections). 2. Power on the display. 3. Plug the power supply into the 2-pole captive screw power connector on the switcher rear panel.
Using the Optional IR 102 Remote Control The optional hand-held IR 102 Remote Control (part number 70-224-10) lets you remotely perform functions that are also available through the front panel buttons and SIS commands. The IR receiver port on the front panel is located to the right of the Auto Switch LED.
Locking and Unlocking the Front Panel (Executive Mode) Front panel lock mode disables all front panel controls, locking out users from those functions (RS-232, USB, and IR control remain available). Putting the switcher in lock mode enhances security by protecting against inappropriate or accidental changes to settings. If a front panel button is pressed during lock mode, all front panel LEDs blink once.
User-assigned EDID mode In this mode, you can select an EDID file that is stored on the switcher at the factory. The selected EDID is stored in memory for the inputs and is not overwritten; the switcher does not automatically obtain EDID information from the display. You may want to use this mode if there is a problem with automatic communication of the EDID information from the attached display, and you want to ensure that the correct information is stored on the inputs.

They are designed to be used with computer sources. • HDTV: These are video rates standardized by SMPTE and CEA. They are designed to be used with video and computer sources. Video format 2 • DVI: These are 128-byte EDID files, which specify a DVI sink.
Remote Communication and Control This section describes remote operation of the SW HDMI switchers. Topics include: • Using Simple Instruction Set (SIS) Commands • Updating Firmware Using Firmware Loader Using Simple Instruction Set (SIS) Commands The SW HDMI can be remotely set up and controlled via Extron SIS commands that are issued from a host computer or other device, such as a control system.
Error Responses If the switcher is unable to execute a command it receives because the command is invalid or contains invalid parameters, the switcher returns an error response to the host.
